Multiuser Detection in Cdma Mobile Terminals de Piero Castoldi

Multiuser Detection in Cdma Mobile Terminals: Artech House Mobile Communications

Autor Piero Castoldi
en Limba Engleză Hardback – 31 mai 2002
This resource aims to provide mobile-communications professionals with a thorough understanding of CDMA (code division multiple access) transmissions and detection. Because CDMA technology provides a highly efficient way to share communication channels among different users, it has been adopted in today's third-generation mobile-communication systems. The book offers practical guidance in designing the latest equipment being utilized in this field. It also describes the open issues of this type of multiple access, introduces the properties of CDMA and investigates in-depth novel and recent CDMA systems.
